Pressure regulator valve stuck in bore

I was installing shift kit in my 700 r4 , went to put pressure regulator valve back in bore, started to go in nice then it was sticky... i gave it a few taps with a screw driver and now it seems to be stuck worse... researching again said tap it more to help un stick... but now it looks hopless... no movement at all... anyone have any advice on how to get this thing out?.. I know the pieces went back in the correct order but I'd feel much better taking it all out...HELP

Typical tranny valves should move freely enough to fall out under it's own weight or w/ a pocket magnet.

Sticky valves are a common cause of tranny problems.

If they are tight you must find and correct problem.

Did you drop the valve?

Perhaps some grit hitched a ride in w/ the valve?

Does the valve exposed end have a open ID?

No where to grab it w/ a bent pick?

Can you pressurize other side to pop it out?

May be able to shrink it w/ liquid O2.

Got a pic?

May try blowing air in the suction hole where filter neck goes.
Needle nose pliers may reach the end of the Pr. valve if Spring & TV,L/R boost valves are removed..

You can have the Bore cut & reamed for a larger valve also.

Sounds like the boost valves is what we are talking about?

sorry guys... I was so frustrated with what had happened... it was the boost valve sleeve that was stuck... I got it out.. must have been some gunk on the bore hole... My next question is ...

I have 20004r boost valve sleeve, boost valve reverse boost valve sleeve and reverse boost valve left over from a 200 4r I worked on... are they the same... just by eye balling them they look the same?... could I just use them as replacement parts?...

Yes, 2004R & 700R4 use the same style valves. The diameter of the Boost valves may be different as they come in several sizes.
